IMPROVEMENT IN HARVESTERS.

Specilication forming part of Letters Patent No. 30,636, dated November 13, 1860.

To all whom it may con/cern:

Be it known that I, NATHAN MAxsoN, of Vilmington, in the county of Clinton and State of Ohio, have invented a new and Improved Grain and Grass Harvester; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, Inaking a part of this specification, in which- Figure lis a side elevation of my invention. Fig. 2is a side sectional view of the same, taken in the line x x, Fig. 3. Fig. 3 is a plan or top view of the same. Figs. Al., 5, and 6 are views of detached parts of same.

Similar letters of reference indicate correspending parts in the several figures.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A. represents a rectangular frame, the back part of which is supported by two wheels, B B, the axle C of which is fitted in suitable boxes, c, on the frame. The wheels B B are placed loosely on their axle C, and are connected therewith, when necessary, by means of catches D D, which may be actuated by levers E E, arranged in the usual way.

On the axle C there is permanently secured a spur-wheel, E, which gears into a pinion, G, on a shaft, H, in the frame A, and on the shaft H there is a pulley, I, around which and a smaller pulley, J, on a shaft, K, in front of the axle C, there is placed a belt, L. To the outer end of the shaft K. there is attached a crankpulley, M, thev pin b of which has a ball or sphere fitting in a socket in the back end of a rod, O, forming a universal-joint connection. (See dotted lines in Fig. 8.) The front end of the rod O is connected in a similar manner to a T-shaped lever, P, which is fitted in the front part of the frame A, at one side, c being the fulcrum of the lever, which passes through the finger-bar Q, near one end, the finger-bar being atthe front end of the frame A. At the opposite end o f the linger-bar there is a lever, It, and to the front ends of the levers P R a sickle, S, is attached, said sickle being of the usual reciprocating kind. To the back ends of the levers P R there is attached a rod,-.T, which may be provided with a nut, d, at one end to admit of the sickle being strained perfectly taut. The rod also may be provided with a spring, c, metal or india-rubber,) in

order to allow the sickle a certain yielding eapacity to compensate `for any irregularity or inequality of strain in the levers P It. y

The outer arm of the lever P is provided with the ball f, which is iitted into the socket at the front end of the rod O. The precise form of the lever P, with its ball f, is shown clearly in Figs. 5 and 6.

In the frame A, and directly back of the Iinger-bar Q, there is placed transversely a shaft, U. This shaft is fitted in suit-able bearings, g g, attached to the frame in such a way that theymay be adjusted vertically, so as to bring the shaft U to the required height. The

shaft U has radial arms 7L attached, to which plates V are attached, the ends of the plates being turned or curved to form sides. These plates V are shown in Fig. 3; but any proper number may be used.

. In the frame A there is placed a longitudinal rod, W, on which a spiral spring, i, is fitted. The spring t' has a tendency to keep the rod W shoved forward to the extent of its movement, and on the rod XV there is a hub or projection, j, against which a pin, k, on the axle C acts as the latter rotates. the rod W, when not restrained,'projects sufiiciently forward to be within the path of ro tation of the plates N, and prevent the movement of the same.

X is a bar, the back end of which is iitted. by arms Y to the axle C, the arms being allowed to turn on the axle. The front end of the bar X is supported by apair of wheels, Z, to the axle c of which the draft-pole b is attached. On the bar X there is a lever, c', the front end of which is connected by a rod, d', to a bar, e', which projects from the frame A, the bar e working on a curved guide-pin, f', attached to the under side of the bar X.

The operation is as follows: As the machine is drawn along a reciprocating motion is given the sickle from the axle C through the medium of the gearing F GQ belt L, crank-pulley M, connecting-rod O, and lever P. In consequence of having the connecting-'rod O attached to the crank-pulley and lever P by the ball-andsocket connection, all unnecessary play and much friction is avoided, and by having the rod T attached to the levers P Rthe sickle may be strained perfectly taut, so as to work through the fingers without producing any greatdegree of friction, the sickle being pre- The front end of lingers.

ping` in line with the finger-bar in consequence` of the previously-,filled plate V being arrested by the rod W, which was thrown forward by l the spring z' as soon as the pin 7c of the axle C passed the hub er projection j on the rod. These revolving plates V form a very simple and efficient grain-discharging device. The

sickle ma5T be raised at any timeby actuating` 4the lever c on bar X.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The arrangement of the automatic intermittently-rotating platforms V between the ngerbar R and dividing-axle C, as herein shown, so that the cut grain will fall over the ngers upon the said rotary platforms and be ldischarged, as set forth.
